Title: Improvements in and relating to collision buffers for railway and like vehicles
IPC: B61G11/08
Filed: 1922-01-07
Abstract: 194,055. Metropolitan Carriage, Wagon, & Finance Co., Ltd., and Robinson, J. G. Jan. 7, 1922. Buffers.-A buffer for a railway vehicle has a spring or set of springs to take up the ordinary buffing strains and a supplementary spring or set of springs to come into action after the first set of springs have been fully compressed; the first set of springs works through the headstock within and in front of which it is housed, and the supplementary spring or springs are situated at the back of the headstock. In the event of a collision, the bolts taking the buffing strains are adapted to break and permit a corrugated collision buffer to come into action. The ordinary buffing spring a is housed in a sleeve b which slides through the headstock and is slotted to straddle the plate j and bear on the compression plate m of the supplementary spring l. The plates j and n are drilled to take the bolts p and are separated by distance pieces s. The bolts p are reduced in section at q in order to fracture under excessive strain. Under excessive buffing, as in a collision, the spring a is compressed until the head of the buffer engages the end g of the sleeve, then the spring l is compressed due to the casing b bearing on the washer m until the bolts p fracture, after which the corrugated buffers (not shown) engage to take the final shock.

Title: Diagnostic system for a machine
IPC: G05B19/406
Filed: 1975-01-07
Abstract: 1477241 Automatic control of testing KEARNEY & TRECKER CORP 7 Jan 1975 [15 Jan 1974] 588/75 Heading G3N In the performance of monitoring/diagnostic checks on at least one n.c. machine at site 10, a diagnostic program of machine operations is transmitted over link 14 from a remote analysis site 12, the current machine response being transmitted back to the site 12 for comparison with data relating to acceptable operating characteristics, and stored machine responses to previous checks. In dependence on the result of the comparison, changes may be made in machine operation, or the need for "down" time, for preventive maintenance, may be indicated. In the performance of a diagnosis, an analyst, for given identification of the particular machine tool and its type, chooses the diagnostic routine, the latter including characteristics of the machine when new, and data resulting from the most recent diagnostic routines performed previously on the machine. The result of the current routine is displayed by means of units 48, 54 or 56, following which the analyst may call up further diagnostic programmes, or inform an operator at the machine site of the results of the test and/or the need for maintenance. Operating parameters that may be checked include drive torque characteristics, a tool slide being moved at a succession of speeds, the corresponding required drive torques being sampled. The resultants are compared with upper and lower limit values and, if within the allowed range, the current values are stored in lieu of the oldest values from previous tests. The trend in the change in torque values is monitored, and if increasing excessively the drive lubrication is increased subject to a maximum and a further test is specified in a lesser time than normal. Should the lubrication limit thus be exceeded, or a minus trend in the torque requirement is detected, a backlash test is instigated which if providing an excessively high result, leads to an indication that the machine requires maintenance. If the latter result is not excessive, frequency, and SCR firing phase tests of the A.C. motor drive are performed, and may indicate failure of the control circuit. In the event of malfunction, the current machine data is not stored. Other programs in the diagnostic routine may include performance at low, medium and high feedrates and rapid traverse, monitoring of servo axis following errors, and stability, overshoot at a variety of speeds, and settling time of the servo at a given commanded position, operation of an automatic tool changer, and that of the machine computer and tape recorder. The analyst may observe the machine in operation by a video link, telephone handsets HS being provided. The diagnostic routines may be performed during tool manufacture, or after installation. An alternative form of system organisation is displayed in Fig. 8 (not shown). In the testing of the drive torque characteristics, the latter is determined as a function of the frequency and SCR triggering phase of the drive motor control.

Title: Automatic packaging machine
IPC: B65B41/18
Filed: 1955-01-11
Abstract: 764,552. Packaging machines. PACKAGE MACHINERY CO. Jan. 11, 1955 [Jan. 15, 1954], No. 887/55. Class 94(1). [Also in Groups VIII, XVI and XL(b)] A machine for forming a tube from a printed or like web of material, filling the tube as it is formed and sealing it transversely to produce packages, comprises sealing and clamping jaws which grip the tube to draw it down, the jaws travelling a distance greater than the desired package length and opening before the end of their downward stroke, the opening being controlled by regularly spaced markings or indications on the web, thus ensuring accurate positioning of printing on each package. A duplex machine is described in which the markings on the web are scanned by photo-electric means to regulate the point of opening of the jaws. The webs M are fed from rolls R, the rotation of which is controlled by braking means (see Group XVI) over horizontal shelves 42 to known tube forming devices 12, which may be as described in Specification 440,328. As the tubes leave the devices 12, they are gripped between heat sealing jaws 95, 103 carried on a pair of vertically reciprocating frames 78, 79 on a head 13. The frames are reciprocated by vertical movement of shafts 67 carried on a crosshead 65 operated by cam means 49 on a shaft 48. The shafts 67 are rotatable by a hydraulic piston moving a rack 72 mounted on the crosshead 65 and engaging pinions 70. Rotation of the shafts 67 causes the jaws to close at the top of their stroke. The tubes are each scanned by a photo-electric eye 109 which reacts to, say, spots P at package length spacing to permit hydraulic means 104 to be actuated and open the jaws 95, 103. At the same time, solenoids 47 operate to cause pads 44 to clamp the webs against the platforms 42. During the downward stroke of the jaws, knives 111 carried between vertically spaced pairs of sealing faces of the jaws cut off the filled package lengths between the pairs of transverse seals (see Group VIII). The longitudinal seams of the tubes are heat sealed by elements 18 pivoted on rods 121. The means for filling the packages are not described.
